When you write a class in Java, it's hard to change it dynamically.

The small partners in iOS development should often use DER and P12 for encryption and decryption, and in the usual encryption more than one encryption algorithm, you can add a bit of salt it ~ This article mainly describes the OPENSLL-based RSA encryption in iOS. A total of two ways, one is based on P12 encryption and decryption, there is a blog park officially provided by the public key string encryption, in fact, the two are similar, but in iOS support for the CRT format encryption, in fact, it is the same bar ~ See the following two kinds of encryption applications.

In the previous section, we successfully passed the data from the foreground JSP page to the controller layer, but did not write the service layer, honestly there is still a lot of work not, especially with the database links, so, this section, we specifically to deal with the database connection aspects of things.

Say to Qt compile, really lead people sad ah, not only compile options a lot, and compile time is relatively long, always can make want to compile QT source of people deterred, hehe ... I am one of them, do not know from when to start to think of Qt source code compiled, but also tried several times, but all failed to end, compile the time is always to no avail, the relevant articles on the Internet is a large, but always a variety of, because different people's machine is not the same,  A different error message may occur when compiling the source code. http://www.cnblogs.com/tusvartj/

queryForList method is a common method in the actual development, it means that if you query from the database 10 data, then a list wrapped up, each piece of data is a map.

Either using JSON, etc., in the new ASP. Microsoft has provided us with a dependency injection function by default, we no longer need to use third-party components to implement dependency injection, but sometimes we want to configure dependency injection in the configuration file, and Microsoft's own DI The component does not provide us with a configurable file, then we need to implement the functionality of this configuration item ourselves.  Personally, the main use of the scene is some in the compile time can not be determined to implement, need to dynamically modify the implementation of the place. http://www.cnblogs.com/jycunet/

The recent period of time is learning JavaScript, too much knowledge, need to carry out the actual use and summary, the National Day holiday just have time, wrote the following on the JavaScript summary, may be the understanding of the event is not perfect, I hope readers a lot of guidance, shoot bricks, I would be grateful. All right, just title it.

At the same time is a difficult point. I collated the study notes to facilitate learning, but also to deepen their impressions. This part of the code is a lot of detail, need repeated deliberation. So let's get started.

Of course, there are a lot of open-source on the net than the landlord to write more good, only for reference, haha http://www.cnblogs.com/gerujwq/

First of all, otherwise fantasy does not come out what kind of, front-end style is very low, after all, the main is to say backstage, the front-end for simple test simple to write out, like the good style can adjust their own AH

If you want to execute two or more function at the same time, then you must open one or more threads, this is the generation of multithreading. I think the first birth of multi-threading is from this!

Functionally, B-tree is designed for disk or other storage devices, can effectively reduce the number of disk I/O operations, so we often see that there are many database systems using B-tree or B-tree variants to store data structures, structurally, B-tree nodes can have a lot of children, from a few to thousands of, This typically relies on the cell characteristics of the disk being used.

You've probably heard a lot of things before, like data sources, connection pools, c3p0, and so on. Being a novice is easy to scare by these nouns, because the general training organization will not tell you this, they just give you the most basic JDBC, in general, is to tell you to use Java code to manipulate the database a few steps. http://www.cnblogs.com/ejrtujw/

But I think when compiling qnetwork may also need this library, personal feeling compiled QT source code is a big challenge, not because he is difficult to compile, mainly QT compilation options and his SDK cross-platform.

Finally to the Queryforbean, this method means that the query out of a data (note, can only be a piece of data) into JavaBean, that is, a Java object.

For example, I look up a piece of data from the T_user table and then it can return a user object to me. Obviously, this approach definitely needs to use the Java Reflection API and generics.
